The Alaska Dispatch News reported that Miller called for House Republicans to seek impeachment at a Chamber of Commerce candidate forum on Wednesday.

“I think we all agree that Obama’s out of control,” Miller said.

Miller, who upended the Alaska Senate race in 2010 when he beat incumbent Lisa Murkowski (R) for the GOP nomination but then lost the general election to Murkowski's write-in campaign, joined the impeachment caucus late last month. It appears that former Alaska Gov. Sarah Palin inspired him.

"Sarah Palin is right; it’s time to impeach this President for dereliction of duty, selectively enforcing the law, and usurping powers that the Constitution does not authorize," Miller said in a statement on July 21. "He is willfully undermining the rule of law and creating chaos.”

Miller is currently polling third in the 2014 Alaska Republican Senate primary, according to TPM's PollTracker, with an average of 20.5 percent of the vote.

According to the Dispatch News, Miller asked the GOP frontrunner, former attorney general Dan Sullivan, about impeachment on Wednesday. Sullivan agreed “110 percent that this administration is out of control,” but declined to endorse impeachment outright.

Sullivan did say he would take the issue seriously if the House impeached Obama and the question reached the Senate, the newspaper reported.
